Michal Kubecek 3424170f37 tun: replace tun_debug() by netif_info()
The tun driver uses custom macro tun_debug() which is only available if
TUN_DEBUG is set. Replace it by standard netif_ifinfo(). For that purpose,
rename tun_struct::debug to msg_enable and make it u32 and always present.
Finally, make tun_get_msglevel(), tun_set_msglevel() and TUNSETDEBUG ioctl
independent of TUN_DEBUG.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
